BOM Introduction
General
Notes on the Bill of Materials: The quantities check out with the Parts Inventory on the GenesisRadio website with one exception:
- The web site states that 29 10k 1/4W Resistors are supplied;
- The stages, combined, call for 30 10k 1/4W resistors.
Hopefully, this discrepancy was overlooked on the web site and 30 were actually provided in the kit as shipped.
